I had to do a complete tear down on my B7610. Water got into the oil. I got everything put back together and had to redo because of a timing issue. It would turn over, just not start with white smoke coming out of the exhaust. I reset the timing and came back to turn over and now I have nothing. There is no power at the dash, no fuel solenoid click, nothing. I have replaced all fuses, replaced 30a slow burn fuse., and checked to make sure all grounds were bolted up. I have 12v at starter and starter solenoid when turning the key. There is power in the harness at the dash. Any help would be greatly appreciated.

Sounds like a bad battery or bad connection between tractor and battery. Try cleaning the battery posts and terminals as a first step. Then try jumping with a known good battery.

A flat 12 volts may not indicate enough voltage and amps to get you going. You can have the battery tested at auto parts store.

Sometimes the battery cables have degraded internal to the insulation and can’t pass enough amps to crank.

Seems that even with a bad battery you should get some power to the dash, etc. If you have an electrical diagram start at the battery and trace to a point where there is no power.

As far as bad batteries...
I've had batteries that were on maintainers/chargers overnight and read 12.6 volts not have enough Amps to turn over an engine. Bought a Battery Load Tester from Harbor Freight for $18. It's not a top-of-the-line digital unit but it works very well for occasional use, money well spent and a time saver.

It went from cranking normally to ... nothing. That's not a bad battery. It's probably not a corroded connection.

Do a load test at the starter where you have 12v. Here's why.
